Channel Attributes

Note

AINx: Analog input channels
MINx: Miscellaneous input channels. You can use VkDaqGetDeviceAttribute and VkDaqSetDeviceAttribute to read or write the MINx data source. For example, set the "dev1/MIN1" data source to encoder "Encoder1"
DINx: Digital input channels
AOUTx: Analog output channels
Read: Attributes can be read
Write: Attributes can be written
Modify: Attributes can be modified during data collection
Save: Attributes can be saved to ini files

1. Use VkDaqGetChannelAttribute to Read device attributes.
   For example: Read the device sampling frequency.

   char inputType[65536] = {0}; int ret = VkDaqGetChannelAttribute("dev1/AIN1", "InputType", inputType, sizeof(inputType) - 1); 

   
   
2. Use VkDaqSetChannelAttribute to write device attributes.
   For example: write the device sampling frequency.

   int ret = VkDaqSetChannelAttribute("dev1/AIN1", "InputType", "100000");
